The 26-year-old signed for the Portuguese giants last European summer and, having netted 20 times in 19 league appearances so far, the Colombian international looks to be filling the goalscoring void left after Falcao's move to Spain two years ago.

But the former Jaguares striker believes he should be judged on his own merits.

"First of all, I don't like comparisons because I think that everybody has their own style of play," he told Uefa.com.

"Falcao wrote his history here at this club and I'm just starting mine.

"In terms of looking at Falcao as a rival, people might think that but it isn't true. I'm good friends with Falcao, and I see him as a good person and that he is doing his best, just like I do."

The forward also refused to look beyond Tuesday's Champions League clash with Malaga in discussing his team's aspirations, but believes Porto could prove the surprise package of this season's competition.

He added: "I think that nothing is impossible. We will try and I think we have a team that could succeed. But for now, before thinking about winning it, we have to think about the next stage and that is the tie against Malaga."
